3 Claims. (Cl. 211-60) This invention relates to tubing racks, and

more particularly to an improved tubing rack for supporting welldrilling pipe on a derrick.

It is an object of this invention to provide an improved pipe rack ofthe kind to be more particularly described hereinafter, which isrelatively portable so that it may readily be attached to or removedfrom the platform of a derrick or the like.

Another object of this invention is to provide a tubing rack of thiskind having a plurality of spaced apart rods against which and betweenwhich the drilling pipes may be supported against the side of thederrick. Pipes held between the rods are securely held in place in anyselected order and are held from rolling or piling up against thederrick. The supporting rods are pivotally mounted on a base so thatthey may be folded back out of the way when all the pipes have beenremoved from that rod. By folding out of the way, a clear space isprovided on the derrick platform so a man may easily reach the nextpipes.

A further object of this invention is to provide a tubing rack of thiskind having a base which is provided with clamping Jaws for attachingthe base removably to the planks which form the platform on the derrick.A fixed Jaw,is formed on the base and a movable jaw is supported on thebase, the movable jaw being operated by a lever rockably supported onthe base frame, the movable jaw having a certain amount of adjustment tofit various sized planks.

With the above and other objects in view, my

invention consists in the arrangement, combination and details ofconstruction disclosed in the drawings and specification, and then moreparticularly pointed out in the appended claims.

In the drawings,

Figure 1 is a top plan view of a tubing rack constructed according to anembodiment of this invention,

Figure 2 is a transverse section taken on the line 2-2 of Figure 1,

Figure 3 is a longitudinal section taken on the line 3-3 of Figure 1,

Figure 4 is a fragmentary longitudinal section taken on the line 4-4 ofFigure 1,

Figure 5 is a fragmentary end elevation taken on the line 5-5 of Figure1,

Figure 6 is a fragmentary section taken on the line 6-6 of Figure 1.

Referring to the drawings, the numeral l0 designates generally a frameof a derrick used 2 in oil drilling or other drilling operations,elongated pipes as H for the drill rods.

A platform l2 formed of boards 14 is provided at the upper end of thederrick l0 and is supported on the platform forming members IS. The tuberack l6, constructed according to an embodiment of this invention, isadapted to be clamped to the boards l2 for supporting the pipes H besidethe derrick Ill.

The tube rack I6 is formed of a rectangular frame I! having tubesupporting rods l8 pivotally supported thereon. An elongated rod I9 isfixed on the frame ll by engaging the upper end of supporting arms 20fixed to or formed on a pair of opposite side members of the frame II.

The rod 19 is supported intermediate the length of the side members ofthe frame and the pipe supporting rods I8 are rockably mounted on therod I9. Short sections of tubes or sleeves 2| are loosely carried by therod IS in close end abutting relation and the supporting rods 18 arefixed to the sleeves 2| by welding or other suitable fastening devices.In this manner the rods 18 are freely rotatable about the rod I9 on therack ll.

The rods l8 are adapted to extend from one side of the rack I6 so thatthe tubes or pipes ll may be supported between adjacent rods l8 in theirextended position. As the rods l8 extend using from the rack l6 theyalso extend outwardly from the platform l2. In this position of the rodsHi, the tubes II are adapted to be engaged between a pair of rods [8 forsecurely supporting the tubes II in selected position. As the tubes orpipes II are removed from the rods l8, the rods may be pivoted or rockedabout the rod l9 so that the rods I8 are disposed within the confines ofthe platform I2. In this manner free access may be had to the pipes l Iwithin the remaining supporting rods I3 by an operator without steppingover the rods [8 from which the tubes II have been removed.

The pipe rack i6 is adapted to be clamped onto the platform l2 and is soconstructed and arranged that the rack l6 may be installed on anysuitable platform when it is needed and may be removed when all thepipes have been used.

The construction of this pipe rack is such that it may be manufacturedalone and need not be formed as a part of the derrick III.

A fixed jaw member 22 is fixed to or formed on the forward edge of theframe H at each end thereof. The fixed jaw member 22 may extend the fulllength of the forward frame member and is formed of a substantiallyL-shaped metal bar. The vertical arm 24 of the jaw member 22 is 3adapted to overlie the side edge of the outer board I and the horizontalarm 25 is adapted to underlie and engage beneath the forward edge of thesame board.

A movable jaw member 26 is carried by the rear edge of the tubesupporting rack IS. The

movable jaw member 26 is formed of a substantially L-shaped jaw having avertical arm 21 for abbuttingly engaging the outer edge of the other endboard ll of the platform i2.

The lower arm 28 is adapted to clampingly engage beneath the board Itbelow the arm 21. A forwardly extending arm 28 is fixed to the upper endof the vertical arm 21. The connecting arm 29 extends forwardly andupwardly for pivotal engagement with a lever arm 30 rockably mounted onthe frame H. An elongated pivot rod 3| is loosely supported along therear edge of the frame II by a pair of upstanding supporting members 32at the opposite ends thereof. The lever arms 30 are fixed to the shaft3i for rocking movement therewith.

An elongated operating lever 34 is fixed on the shaft 3| intermediatethe length thereof for the rotation of the shaft by an operator. A meansis provided for locking the lever 34 and shaft 3i in selected positionrelative to the frame H. A spring-pressed keeper 35 is carried by thelever 34 and is adapted to engage in the notches 35 of a segmentalarcuate locking plate 31. The looking plate 31 is fixed to the rearframe member of the frame 11. A handle 38 is pivotally mounted on thelever 33 for disengaging the keeper 35 from the notches 36 for movementof the lever 35 and shaft 3 l. The movable jaw member 26 is adapted toengage the side edge of one of the outer boards it of the platform l2and may be moved into clamping engagement by rocking of the controllever 33.

In the use and operation of this tube supporting rack IS, the front jawmember 22 is initially engaged over the forward edge of the forwardplank It. With the control handle 33 moved to a substantially horizontalposition so that the movable jaw member 26 is in its extreme adjustedposition, the jaw member 26 is disposed as closely as possible inengagement with the rearmost board it. By rocking the control .lever 34to an erect position or as nearly erect as possible, the crank lever 30is rocked forwardly carrying with it the movable jaw member 26. Themovable jaw member 26 is loosely connected as by a pivot pin 38 to thecrank arm 30 and clampingly engages the platform I: between the fixedjaw member 22 and the movable jaw member 26.

For bracing the extended tube supporting rods I8 in their extendedposition, a notched plate 40 is fixed to the forward edge of the frameI! and extends upwardly therefrom. The plate 40 is formed with alongitudinally disposed series of notches 4| within which the rods I.are adapted to engage in their extended position. In this manner therods l8, while supporting the tubes II, are supported on. the frame IIby both the rod l9 and the plate 40. When the rods ll are moved to theirrearmost position they are raised from the notches M and will looselylie above the shaft 3|.

I do not mean to confine myself to the exact details of constructionherein disclosed, but claim all variations falling within the purview ofthe appended claims.

What I claim is:

1. A pipe rack comprising a frame, a rod mounted across said frameintermediate the length thereof, pipe supporting rods pivotally mountedon said first rod, a notched member on said frame parallel to and spacedfrom said first rod, each of said pipe supporting rods engageable in oneof said notches in said member in one position and rockable therefrom toan opposite position, a fixed clamping jaw on said frame, a movableclamping jaw carried by said frame coacting with said fixed jawforclampingly securing said frame on a support therefor, and meansrockably carried by said frame for moving said movable jaw.
